ABSTRACT:
A multi-cyclone dust separator according to an embodiment of the present invention comprises at least three dust separation units for separating dust stepwise from relatively larger size. The dust separation units comprise a first dust separation unit primarily separating dust from external air drawn in; a second dust separation unit secondarily separating dust from the air primarily dust-separated by the first dust separation unit; and a third dust separation unit thirdly separating dust from the air secondarily dust-separated by the second dust separation unit. Here, the first to third dust separation units are multi-layered in a serial manner.
